SPECIFICATION forming part of Letters Patent No. 644,494, dated February 27, 1900.

Application filed November 16, 1899. Serial No. 737,230. (No model.)

To ttZZ whom it may concern:

Be it known that I, CLYDE MORDIGABRADY, a citizen of the United States, residing at Brunswick, in the county of Glynn and State of Georgia, have invented new and useful Improvements in Siphons, of which the following is a specification.

My invention relates to improvements in siplions, and pertains to a siphon which is automatic in its operation after it has once been started, all of which will be fully described hereinafter and particularly pointed out in the claims.

My invention is especially adapted and intended to be used in connection With tanks, barrels, and other'receptacles, whether metal or other material, which contain volatile liquids, such as gasolene, coal-oil, wines, and liquors of all kinds.

The object of my invention is to provide means for keeping the receptacle absolutely air-tight when the siphon is not in operation to prevent any evaporation of the liquid and Which is so constructed that when the siphon is in operation there is no escape of the gases from the liquid which fills the empty space of the receptacle, whereby all evaporation, and consequently waste, of the liquid contained in the cask 'is prevented, and also whereby the siphon is always ready forautomatic operation when it is desired to draw any quantity of the liquid from its receptacle.

In the accompanying drawings, Figure l is a perspective view of my invention, showing it applied to a barrel. Fig. 2 is a transverse sectional view taken through the siphon-tube and the barrel or tank. Fig. 3 is a detached perspective view of the bung and its attachments, with the curved and depending portion of the siphon-tube removed. Fig. 4 is an inverted detached perspective view of the bung and its attachments, the curved and depending portion of the siphon-tube being removed therefrom. Fig. 5 is a sectional view of a portion of a pump connection, showing the check-valve therein. Fig. 6 is a vertical sectional View of the upper end of the tube.

Referring now to the drawings, A is a barrel, tank, or other vessel, which is provided with a bung-opening B, said bungeopening being internally screw-threaded, as shown. The bung-opening is here shown in the side ing the spirit or scope of my invention.

of the cask, though it can be placed in the end of the cask without in any manner afiect- Fitting within this bung-opening B is the depending externally-screw-threaded flange C of a bung D, the said bung having flat sides, as illustrated, for the purpose of enabling it to be screwed Within the bung-opening by means of a suitable wrench. Situated under the horizontal portion a of the bung and between it and the outer face I) of the bung is a Washer E for the purpose of affording an air-tightjoint. Also for the purpose of facilitating the making of this air-tight joint the bung-opening has the portion 5 extended slightly above the outer side of the cask and is provided with a level smooth surface. The bung is provided with three transverse openings, the one 6 receiving at its inner end a depending pipe G, which reaches to about the bottom or lower side of the cask and is provided with notches f, and screwed in the outer end of the said opening is a verticallydisposed short pipe g. The openingt' has its inner end communicating with the interior of the cask, and screwed in its outer end is a short vertically-disposed pipe j, the said pipe having between its ends a valve or cook I, by means of which the said pipe can be closed. The opening is has its inner end also in communication with the interior of the cask and its outer end receiving a short tube J, which is furnished with a Valve or cook K, by means of which the said opening can be closed or opened as desired for the purpose of permitting air to pass through the said pipe within the cask in a manner and for a purpose to be described hereinafter.

The upper end of the pipe 9 is provided with a concaved socket Z, being externally screwthreaded, as shown at m, and this concaved socket is adapted to receive the convex end of a socket n upon the upper end of a curved and depending siphon-pipe L, constituting an inverted-J-shaped siphon-leg. The convex socket is provided just above the conveXed portion thereof with a flange 19, with which a flanged nut M engages, the said nut adapted to also engage the screw-threaded portion of the concaved socket for the purpose of uniting the siphon-pipe with the concaved socket, and consequently the pipe to which it is attached,

and to form a tight joint therewith. The lower end of the siphon-pipe is provided with a valve or cock N of any desired construction for the purpose of opening and closing the 5 said pipe in the operation of the said siphon,

as will be described hereinafter.

The upper end of the pipe J is provided with an internally-sorew-threaded openingagadapt ed to receive the screw-threaded end of astem I0 8, the said stem having a longitudinal openshown to be an ordinary bicycle foot-pump and the opposite end of the said pipe is constructed for connection with the check-valve 25 tube in the manner here shown.

In operation the valve I is opened and air is forced within the tank sufficiently to cause the siphon to operate when the. valve N of the siphon-pipe is opened, as is readily un- The said valve is then closed, and the siphon is ready for automatic operation. To operate the siphon, it is only necessary to open the valve N in the outlet end of the siphon-tube,

and the siphon will operate until the air-pressure within the tank has been reduced. 'When this condition is reached, the siphon is then operated by the opening of the siphon-pipe valve and of the inlet-valve K to permit an 40 admission of air within the tank to allow the siphon to operate.

From the above construction it will be seen that I have produced a siphon which is absolutely air-tight when not in operation, thus 5 preventing any evaporation of the liquid contained within the tank, and which when the siphon is in operation will also prevent the escape of any gases or vapor within the tank, owing to the fact that air will pass in through the inlet-valved pipe J during theoperation of the siphon, and when the siphon is shut ofi? the inlet-pipe is also closed by means of its valve.

To start the operation of the siphon, the inlet-valve K is opened and then the siphonpipe valve opened and the desired quantity of liquid withdrawn from the tank. \Vhen it is desired to stop the siphon, the siphonpipe valve is closed and then the inlet-pipe 6o closed, which then forms an air-tight tank and prevents absolutely the evaporation of any liquid contained therein. It will also be noted that the pump may remain attached to the short section P of the flexible or rubber tube or detached therefrom, as desired, for any escape of the vapor or gases through the said pipe is prevented by means of the valve K in the air-pipe J, extending from the bung.

The object in making the siphon-pipe in sections, as here shown, is to enable the bung to be screwed into its socket. Otherwise the depending end of. the siphon-pipe could not be screwed into its socket, as will be readily understood.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A siphon comprising a bung adapted to be air-tightly fit to a tank, cask or other vessel, a siphonpipe passing through said bung into the cask and to near its lower side or end, the outer projecting end of the siphon doubled downward to a point below the liquid level of the said tank, a pump communication through the said bung within the cask, apump connected with the said communication, and a valved air communication through the said .bung independent of the said pump, substair tially as and for the purpose described.

2. A siphon comprising a bung adapted to be air-tightly fit to a tank, cask or other vessel, a siphon-pipe having one stem passing through the bung within the cask and its 0pposite end doubled and extending downward outside of the said cask, the lower end of said outside portion provided with a valve, a valved pump communication through the said bung within the cask, a pump connected with said valved communication, and a valved air communication through the said bung independent of the said pump, substantially as and for the purpose described.

A siphon comprising a hung adapted to be air-tightly fit to a tank, cask or other vessel, said bung having a passageway extending vertically therethrough, a pipe depending from said passage-way, a siphon-pipe also connected with said passage-way and extending to or below the lower end of said depending pipe, an air passage-way having a valve, a pump connection with said air passageway, and a passage-Way through the said bung independent of the pump passage-way and having a valve, substantially as and for the purpose described.

4. A siphon comprising a bung adapted to be air-tightly fit to a tank, cask or other vessel, said bung having a passage-way with a depending pipe, a siphon-pipe also connected below the lower end of said depending pipe, the bung having an air passage-way, a manually-operated valve within said air-passage, a pump connection with said air-passage, said pump connection having a check-valve, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
